[PATCH] cleanup of compat_ioctl functions
From: Arnd Bergmann
Date: Wed Oct 08 2003 - 11:17:49 EST
This is my reworked patch for cleaning up compat_ioctl, with the main
purpose of making it usable for s390. Every single change here should
be trivial, but there are a lot of them.
The changes are:
- audit all 32 bit pointer accesses and make them use compat_ioctl(),
because of the necessary conversion on s390
- introduce ULONG_IOCTL() which is used instead of COMPATIBLE_IOCTL()
for all ioctls that have their argument encoded in 'arg' instead
of the memory pointed to by arg. Same reason as above.
- strictly use 'int h(unsigned, unsigned, unsigned long, struct file*)'
prototypes for all handlers called from sys32_ioctl. Not required,
but type checking is usually considered a good idea.
- mark (almost) all user space pointers with '__user' for use with
sparse. This found one error in sg_build_iovec() where a user
pointer is dereferenced.
- remove most #ifdefs in <linux/compat_ioctl.h>: They don't make
any sense if the respective handlers in fs/compat_ioctl.c are
not disabled as well and they are potentially harmful (the
CONFIG_BLK_DEV_DM e.g. was insufficient).
- comment out COMPATIBLE_IOCTL(SIOCSIFBR) and
COMPATIBLE_IOCTL(SIOCGIFBR), they appear to require a handler
BTW: while auditing the COMPATIBLE_IOCTL list for possible uses of
direct argument passing, I found no real handler for these ioctls:
- SIOCSIFLINK, SIOCSRARP, SIOCGRARP, SIOCDRARP
- BLKSECTSET
- CLEAR_ARRAY, SET_DISK_INFO, WRITE_RAID_INFO, UNPROTECT_ARRAY,
PROTECT_ARRAY
Does anyone know whether they are all still needed or what happened
to them?
